SYLVESTEB D. SHOEMAKER, OF GROGAN, OHIO.

SHEET-METAL GUTTER.

To all whom it may concern:

Be it known that I, SYLVESTER D. SHOE- MAKER, citizen of the UnitedStates, residing at Grogan, in the county of Franklin and State of Ohio,have invented certain new and useful Improvements in Sheet-MetalGutters, of which the following is a specification.

My invention relates to sheetmetal gutters and has for its object, theprovision of a sheet metal gutter constructed in such manner that anunbroken water-way is provided therethrough without weakening thestructure or causing the metal to become unduly distended or cracked.

Further objects and advantages of the invention will be set forth in thedetailed description which now follows.

In the accompanying drawing: Figure 1 is a plan view of a portion of asheet metal gutter corner, Fig. 2 is a vertical section thereof uponline q z of Fig. 1, and, Fig. 3 is a vertical section thereof upon linezr-w of Fig. 1.

Like numerals designate corresponding parts in all of the figures of thedrawings.

Attempts have been made heretofore to stamp out a gutter corner such asis shown in the drawing and to make said corner a rounded one in orderto provide a continuous and unbroken water-way for the passage of thewater, but it has been found that where these gutters are stamped outunder comparatively little pressure, they buckle and form ridges at thecorners, said ridges tending to obstruct the passage of leaves, twigsand the like and ultimately stopping up the gutter, while when thepressure is sufficient to force out all of these ridges, it is greatenough to so distend and strain the metal, that it is often broken andalways so thin that it easily rusts through, for even though thesegutters are made of galvanized metal, corrosion will set in around theleast crack formed in the metal by undue strain. It is to provide agutter having all of the advantages of a continuous and unbrokenwaterway with none of the disadvantages incident to undue strain uponthe metal, that the present invention is particularly designed.

In the drawing, the numerals 5 and 6 designate the gutters stamped outof the corner piece 7. The die from which this piece is stamped, is soarranged as to form a portion 8, narrow at the top and graduallywidening toward the bottom, which is curved to conform to the curvatureof the gutter Specification of Letters Patent.

and which lies substantially at an angle of 45 degrees to either thegutter 6 or the gutter 5. At the outside edge a portion 9 is formed inthe gutter, which also lies substantially at an angle of 45 degrees tothe gutters 5 and 6, and which likewise conforms to the curvature of thegutter (see Fig. 2). By forming these angularly disposed portions 8 and9, the true curvature of the gutter is preserved without the formationof any ridges and without unduly straining the metal.

From the foregoing description, it will be seen that simple andeflicient means are herein provided for accomplishing the objects of theinvention, but while the elements shown and described are well adaptedto serve the purposes for which they are intended, it is to beunderstood that the invention is not limited to the precise constructionset forth, but includes within its purview such changes as may be madewithin the scope of the appended claims.

What I claim, is:

1. A stamped. sheet metal gutter having substantially semi-circularportions in cross section which lie at right angles with each other andportions which lie at an angle to both of the first named portions thelatter portions exhibiting a straight line in horizontal section.

2. In a device of the character described the combination with gutterportions which lie substantially at right angles with each other andwhich exhibit a substantially semi-circular cross section of connectingmembers located at the juncture of said gutter portions said connectingmembers exhibiting a straight line in horizontal section, and saidmembers being tapering.

3. In a device of the character described, the combination with gutterportions which lie substantially at right angles with each other andwhich exhibit a substantially semi-circular cross section, of aconnecting member which lies at an angle to both of the gutter portions,said connecting member exhibiting a straight line in horizontal sectionand said connecting member being narrow at the top and wide at thebottom.

In testimony whereof I affix my signature in presence of two witnesses.
